Born in the future, I am the famous 25 Star GENARAL, Weevelo Zapp Brannigan. I have come back in to study sexily in the 21st century and need a new first officer. That Kiff fellow was cramping my style.

What is the word for something that is non-divisible?I guess perhaps I asked in the wrong forum.

But I guess indivisible will have to do for now.
